CONGRATULATIONS on a wonderful decision!
I didn't even want a 12-string until I happened to try a Taylor GA3-12 at GC on a whim. As you (and most everyone says) the playability on this model is out of this world!!
Just smooth as butter right out of the box and the GA body size is really comfortable. I find myself playing practically everything that I used to play (and still play) on my 6-strings on the Taylor 12 and enjoying a whole extra level of sound! After experimenting with lots of different 12-strings before settling on the Taylor, I honestly do not think I'd buy another make or model ... the little GA3-12 does everyhing I was expecting a 12-string to do and it does it with minimal extra effort on my part.
And did I mention that it stays right in tune with almost no adjustment necessary day-to-day? 30 seconds with the Snark and I'm ready for an entire day in perfect concert pitch!
I sorta love my GA3-12 ... can ya tell??
BTW: If interested, here's a little demo:
